Thank you for making the nested screw. I am an inventor and thought I would have to make it from the twist containers. I am making a shape shifting robot. The stls are done and the design has been checked out. Could you please tell me how to get in contact with you in a non public way. My existing patent is for flat packing technology which enables me to make shape shifting robots and I can use the nested screw to extend and retract the shape shifting segments. I have a facebook account under blaine newcomb.
